and enclosedeonstitutes a containing chamber for lubricant, with which manifestly the surfaces between which there is turning motion may always be kept flushed." Furthermore, these surfaces and the body of lubricantv too, are wholly protected from the ingress of dust and other gritty matter. Ducts for introducing and removing lubricant from this chamber are indicated-vat 23 and 43, the one extending through the body of the'axle'box the other through the body of the wheel. llither or both such ducts may be provided. The ducts will of course be properly covered with removable closures.

A lubricant well 24: in the axle box may or notbe provided. 7 ig.. I 'howsbearing rollers 10 interposed between wheel and axle; Fig. II shows surface to surface bearing of wheel upon axle.

Bearing rollers are nowcommonly employed hetweenthe turning )arts in mine car running gear, and man'i estly my invention admits freely of their use. I esire, however, to note that,ineonsequence of my invention, providing as it does a double turning (between wheel' and axle and between axle and axle box), and providing: further a structure in which the bearing surfaces may be flushed always with lubricant, the desirability of roller hearings or of equivalent structure is not so pronounced, and the may, as'Fig. ll indicates,'be eliminate The bushing .45 within-the hub of the wheel of Fig. II is a familiar and obvious detail.

Endwise wear'upon the bearing rollers 10,

when present, is it should parenthetically be remarked) prevented by the arrangement whichcauses axle 3 to be engagedbetween bearingsur'faces 21 and 4L1.

The double union relieves the axle of the wearing efiect of strains otherwise concentrated at the point where itcarries the messes wheel, and generally is nature llexihle' and, I

minutely responsive to'the strains at wrviee.

ll claim as my invention: y

1. ln running gear for a vehicle a'th er part structure, consisting essentially otan axle box, a wheel and an axle, theaxle box containing a cylindrical recess open at the outer end and closed by an integral wall at o the inner end, the wheelbeing-providedin its hub portion with an outwardly axial recess and forming to ether with the axle box,a closed chamber within which the.

axle is wholly contained.

2. In running gear for a vehicle an in} side axle-box containing an elongateeharnher closed inwardl by an integralflwall, said box being adapte hicle body, a wheel provided in its huh porticulated' with both of the two atorenamed parts.

3. In running gear'for a vehicle the coinbination of an axle box provided with a cylindrical recess closed at one end with a thrust wall, a wheel provided with a cylindricaliaxial recess closed at one end with a thrust wall, and. an axle engaging both at said reeesses,-and extending when the par are assembled intolproximity with the op-' posite thrust, walls of the'cornhined named parts, in a union permitting play in longitu .i

nal direction.

In testimony whereof I have hereunto set i w my hand.
